The outer side of the linkage rod 22 is slidably connected with the limit block 23, and the inner side of the limit block 23 is slidably connected with the top plate 26. The inner side of the limit block 23 is equipped with an extension spring 25, one end of the extension spring 25 is fixed to the limit block 23, and the other end of the limit block 23 is fixed to the top plate 26. The left end of the bottom end inside the shell 1 is slidably connected with the second waste powder bin 24;

[0045] Specifically, the elasticity of the extension spring 25 drives the top plate 26, the linkage rod 22 and the arc-shaped cleaning plate 21 to press against the surfaces of the cleaning roller 11 and the spiral cleaning cotton 12, so as to scrape off the waste toner adsorbed by the spiral cleaning cotton 12, thereby improving the cleaning effect of the cleaning roller 11 and the spiral cleaning cotton 12 on the photosensitive drum 8, and the waste toner falls into the interior of the waste toner bin 24, and then the waste toner bin 24 is regularly pulled to clean the waste toner;

[0046] The scraper mechanism includes a waste toner bin 14, a knife block 15, a blade 16 and a spring 17. The knife block 15 is fixed to the right end of the bottom end of the shell 1.

Therefore, the elasticity of the spring 17 drives the blade 16 to clean the surface of the developing roller 9, and the developing roller 9 conveys the toner to the surface of the photosensitive drum 8 counterclockwise, and the blade 16 effectively cleans the toner that has not been conveyed to the surface of the photosensitive drum 8, and the toner that falls into the waste toner bin 14 is processed together to prevent the accumulation of toner on the surface of the developing roller 9.

[0048] Embodiment 3

[0049] Please refer to Figure 7 , an automatically cleanable toner cartridge, an L-shaped support block 18 is fixed at the right end of the shell 1, a limiting plate 20 is rotatably connected to the position of the developing roller 9 inside the shell 1, an adjusting mechanism for driving the limiting plate 20 to control the amount of toner is arranged inside the L-shaped support block 18, the adjusting mechanism includes an electric push rod 19 and a rotating block 27, an electric push rod 19 is fixed inside the L-shaped support block 18, a rotating block 27 is fixed at the output end of the electric push rod 19, the inside of the rotating block 27 is rotatably connected to the limiting plate 20, and a protective pad is fixed at the bottom end of the limiting plate 20;

[0051] The use process of the toner cartridge capable of automatic cleaning provided by the present invention is as follows:

[0052] Working principle:

[0053] The housing 1 is installed inside the printer, and then the toner is placed in the carbon storage chamber, and the servo motor 13 is started to drive the photosensitive drum 8 to rotate, and the photosensitive drum 8 drives the main wheel 7 to rotate, and the photosensitive drum 8 drives the developing roller 9 to rotate in the same direction through the transmission belt, and the photosensitive drum 8 drives the main wheel 7, the transmission wheel 6 and the transmission gear 1 5 to rotate, so that the photosensitive drum 8 and the transmission roller 10 rotate in the same direction, and the transmission gear 1 5 drives the transmission gear 2 4 to rotate, so that the cleaning roller 11 and the photosensitive drum 8 rotate in the opposite direction, so that the developing roller 9 transports the toner inside the carbon storage chamber to the surface of the photosensitive drum 8, and the photosensitive drum 8 prints the toner on the paper. At this time, the developing roller 9 is transported for a long time, and the surface will be accumulated with untransported toner, which will affect the effect of the developing roller 9 on transporting the toner to the surface of the photosensitive drum 8. The elasticity of the spring 17 drives the blade 16 to clean the surface of the developing roller 9, and the blade 16 effectively cleans the toner that has not been transported to the surface of the photosensitive drum 8, and the inside of the waste toner bin 14 that falls is processed together;

[0054] The surface of the photosensitive drum 8 is used to print paper, but part of the toner on the surface of the photosensitive drum 8 is not completely printed on the paper, which will affect the printing effect of the photosensitive drum 8 on the paper next time. The cleaning roller 11 is then rotated to drive the spiral cleaning cotton 12 to clean the surface of the photosensitive drum 8. Therefore, the spiral cleaning cotton 12 cleans the waste toner on the surface of the photosensitive drum 8 for a long time, which gradually causes the cleaning effect of the spiral cleaning cotton 12 to be poor. The elasticity of the extension spring 25 drives the top plate 26, the linkage rod 22 and the arc-shaped cleaning plate 21 to squeeze the surfaces of the cleaning roller 11 and the spiral cleaning cotton 12, so as to scrape off the waste toner adsorbed by the spiral cleaning cotton 12, thereby improving the cleaning effect of the cleaning roller 11 and the spiral cleaning cotton 12 on the photosensitive drum 8, and the waste toner falls into the inside of the waste toner bin 24, and then the waste toner bin 24 is regularly pulled to clean the waste toner.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
